When focusing on Boo Radley’s point of view, you will want to consider Scout’s interpretation of his point of view from the end of the book.
As Scout is walking back from Boo Radley’s porch, she looks back on the events of the book and images his point of view. She imagines all of the events that have occurred, looking at it from his point of view instead of hers.
Fall, and his children trotted to and fro around the corner, the day's woes and triumphs on their faces. They stopped at an oak tree, delighted, puzzled, apprehensive. (ch 31)
This demonstrates Scout’s empathy, and ability to crawl inside another person’s skin as her father asked her to do when she was little.
Boo is not the monster everyone makes him out to be. He is shy and quiet. He is inquisitive. He has a sense of humor. He is brave, because he comes out and puts a blanket on Scout’s shoulders at the fire and he stands up to Bob Ewell when he attacks the children. He clearly sees them as “his” children and takes responsibility for them.
